HARVESTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 253,705, dated February14:, 1882.

' Application filedMay-12,1S8l. (ModeL) To all whom it may concern Be itknown that I, JOHN W. HULL, a cit-i zen of the United States, and aresident of Alquina, in the county of Fayette and State of Indiana, haveinvented certain new and useful Improvements in Harvesting-Machines, ofwhich the following is a specification.

Myinvention relates to an improvement in harvesters.

IO The first part of it consists of a new plan of constructing the frameand the method of locating and combining the driving mechanism foroperating the cutter-bar; and it-consists, first, in providing a pivotedoscillating frame which supports the driving-wheel and drivingmechanism, and transmits its motion to the operating parts through ashaft lying within the axis of oscillation, and forms the pivoted pointof attachment to the main frame which supports the reaping devices.

A second feature consists of supporting the main frame upon acrank-axle, upon the ends of which cranks the supporting mechanism orWheels are attached, whereby the cutter-bar 2 5 and main frame can beraised or lowered in vertical planes to regulate the height of the out.Various other detail features of this part of my invention will be morefully set forth in the description of the accompanying drawings,

0 forming a part of this specification.

The second part of my invention relates to a self-binder which isconstructed and operated so as to seize a sufficient amount of straw andwithdraw it from the bunch to form the hand, and to wrap it around abundle, and then to twist and tuck a knot thereon by the automaticoperation of the device. The several features of this part of myinvention will be fully set forth in the description of the accompanyingdrawings, in which- Figurel is a plan view of the harvester portion ofmy invention. Fig. 2 is a broken side elevation of the pivotedoscillating frame which supports the drivingwheel and driving mech- 5anism. Fig. 3 is a transverse section on line a m, Fig. 1, showing thepivoted shaft broken ofl". Fig. 4 is a broken side elevation of thepivotal end of the oscillating frame, showing one of the pivotal plates,the parts upon which the frame hinges beingin section. Fig. 5 is asidcelevation of the master-wheel, showing its connection withthedriving mechanism. Fig. 6 is a sectional elevation on line 3 3 Fig. 1,partially showing the connecting devices which operate the bindingvmechanism. Fig. 7 is a detail perspective view of the binder. Fig. 8 isa sectional elevation of the binder-table on line 3 3 Fig.7. Fig. 9 is abroken sectional elevation in detail of the devices for twisting andtucking the band. Fig. 10 is a rear elevation of the devices foroperating the reel and carrier, the frame being broken off. Fig.11 is anend elevation, showing the devices for delivering the grain to thebinder. Fig. 12 is a detail perspective view of the binder-arms andtheir operating mechanism, showing them in position when embracing thebundle of grain and ready for the operation of twisting and tucking theband. Fig. 13 is a sectional plan on line 2 a, Fig. 9, of the tuckingdevice. Fig. 14 is an enlarged plan view of the pinion for driving thetucking device, showing the shaft on which it is mounted in section.Fig. 15 is a detail plan view of the gearing mechanism for communicatingmotion to the binder-arms, the shaft on which the arms are hinged beingshown in section.

A represents the ground driving-wheel attached to a proper axle, whichis supported in bearin gs attached to the rear end of vibratory frame B.This supplemental frame is pivoted to the main frame 0 by means of shorthollow sleeve-gudgeons b b, which pass through the rails of the mainframe.

D represents a transmitting-shaft passing through the gudgeons I) b,which forms the axis of the vibratory supplemental frame B.

a a b o 0 represent gearing for transmitting motion to the shaftD fromthe driving-wheel A. o D D represent bevelgears attached to shaft D, fortransmitting motion to the cutterbar and raking mechanism, respectively.

01 represents an ordinary crank-shaft.

61' represents a pitman for giving reciprocating motion to thecutter-bar e.

E represents a crank-shaft, supported in suitable bearings onthe .mainframe 0 G. v

E represents one of the supportingqvheels, journaled on the end of theouter crank of the shaft E.

0 represents the inner crank, which is journaled uponthe rear end'of thevibratory frame B. The frame 0 being supported by being journaled uponthe ends of the cranks of shaft E, and the frame B being supported bythe frame 0 and by the ground driving-wheel A, it is obvious that as thecrank-shaft E is turned on its axial center on the frame 0 G the wholeframe is vertically raised and lowered by the motion of the cranks ofshaft E, and as frame B oscillates on its pivot-centers b b, throughwhich the motion of the driving mechanism is conveyed, the relativeposition of the frame O to the frame B may be changed without affectingthe operation of the operating devices.

The feature of raising and lowering the cutter-bars in vertical planesis a very important one, as it preserves the same angle and pitch of theknives in all positions, and as the cranks of the crank-shaft E can bemade of any desired length a wide range of cutting adjustment can besecured.

The means employed by. me whereby the driver can with his feet readilyraise and lower the entire operating mechanism of the machine consist ofthe following devices:

Frepresents a Windlass-shaft, to which cords F F are attached and woundaround the wheel in the manner of a windlass. The other end of the cordis rigidly secured to the supporting or main frame 0.

G represents an armed wheel rigidly attached to the Windlass-shaft F,which shaft is supported in standards g, of sufficient height to locatethe armed wheel G in easy reach of the driver, and is centrally in frontof him, sothat with his feet resting upon arms ghe may turn the wheel Gand wind or unwind the chain F F, which raises or lowers the main frame0 and adjusts the height of the cutting-bar.

The Windlass can be held in any given position by means of ratchets andpawls or by any other well-known mechanism.

H represents a double-armed crank-shaft, the central portion of whichforms the axis for the revolving reel H. The cranks h h are bent andform gudgeons which are secured in standards h h attached to thereaper-frame.

Sheets 2 and 3 represent the second part of my invention, and relate tothe binding mechanism, which is shown as constructed so as to becombined with the raking apparatus shown in Sheet 1. It can also bereadily combined with various other forms of raking apparatus andplatforms.

J represents the platform.

J represents an endless apron, with carriers 1 Z for raking off thegrain as it falls thereon.

j 7' represent drums, the revolution of which propels the endless apronJ. The power is transmitted to the drums jj from pulley K on shaft K bymeans of suitable belts, k k, and pulley K, and they should be placed onshaft K, outside of and in the rear of the platform, so as to be out ofthe way of the binding mechanism.

L represents a bevel-gear,which meshes with the miter-gear L, attachedto the under side of the binder-table M, and is used to propel theself-raking apparatus which is mounted upon the binder-table M, which isrigidly attached to the main platform J.

M M represent hinged arms, which are pivoted to a central revolvingsleeve, M which projects through the table M, and on the lower end ofwhich is a gear, Q.

m m represent two circular cams, which are used to raise the arms M M asthey revolve around to clasp the bundle in the manner shown in Fig. 12.

O 0 represent band-grapples,which perform the office of clasping andpulling out of the bundle a sufficient amount of straw to form the band.The grapple-points O O are drawn together by means of the rod 0 pullingthe staple or loop 0 into a recess in the end of the arms M as the armsare revolved around on sleeve M P P represent bent arms, upon which thegrain is deposited in bundles, ready for binding. One end of each ofthese arms is securely fastened to the platform M. The free ends ofthese rods lie opposite each other and opposite the arms M when they aredepressed, as shown in Fig. 7.

1) represents fingers attached to the arms P, the upper ends of whichfingers project over the wisp of straw drawn out by grapples O O andseparate it from the remainder of the bundle. The ends of the arms P aremade flexible, so as to move downward as the arms M turn and withdrawthe straw band from the bundle, which passes out of the spaces betweenthe arms P P. Arms M are driven by gears Q Q. The gear Q is providedwith two blank spaces. It receives its motion from Q, which istransmitted through the bevel-gear L L.

It represents a curved ch ate-formed between the apron It and guide-rods0'. The mouth of this chute lies above the bent arms P P, so that thebundles forced through chute R will fall on the bent arms P P.

i represents a hinged guide-rod, which is provided with a catch, 1", anda spring, 1. Arm 1" is caused torise by the pressure of the bundle movedthrough the chute by the revolving of the reel arms S, as shown in Fig.11, so that the pressure of the reel-arm S raises the hingerod 1' andthrows the bunches of grain onto the bent arms P P, ready for binding.As soon as the arm S has passed the point where it discharges a bunchthe spring 1" brings the hinged rod 1' back in position. This motioninterrupts the discharge of bunches upon the binder-table long enough toallow the binding-arm M M to bind a bundle. The reel S is mounted upon ashaft, .9, and is driven by gear S and belt 7c from pulley K and shaftK. The spaces 8 on the face of gear S are for the purpose of cansing thereel S to work intermittently instead of discharging the bunchescontinuously on the binders table. The carriers 6 Z pass each side ofthe arms S, and the grain between the arms S and carriers 1, as it isforced along, presses ITS against the arm S and brings the segments ofthe gear S successively into mesh with the small gear S andintermittently deposits the gathered bunches upon the arm M. The gear Qrests in position as shown in Fig. 15 until a bundle is in the act ofbeing discharged upon the binders table, when the arms S are caused toengage with the spring-trigger T, which pushes arm M forward and causesthe gear Q to move around and mesh with Q, and this sets the bindingmechanism into motion. One com plete motion of the binding mechanism iscom pleted or formed at each semi-revolution of the gear Q.

T represents a standard-arm, on which the twisting and tucking mechanismis mounted.

t represents the driving-pulley mounted on shaft t, which is in motionduring each semirevolution of the gear Q. This shaft t drives twomechanisms, the upper one being operated bypulleys UU, around whichpasses a belt and rapidly revolves a twisting device,V, which is placedvertically above the ends of the arms M as their ends are brought nearlyin contact to clasp the bundle. The ends of the straw, forming a bandwhich projects through the grapples O, are rapidly twisted by the openogee twister V.

To complete the tie I provide a mechanism for tucking the ends of thestraw band between the band and handle, something after the manner ofhand-binding. X represents 7 the tucker, which is provided with a curvedfinger, Y. This tucking device is pivoted upon a hanger attached to theoverhanging arm T, and is provided with a segmental gear, a which isdriven'by a rack-bar, a. This rackbar is driven forward by pinion Bwhich engages with a rack upon one side ofthe rack-bar a.ratchet-andpawl connection, as shown in Fig. 14, so that when shaft t isrevolved the rackbar a is driven forward and carries the tuckerv X Yrapidly around its axial point. The fin ger Y in its path engaging withthe end of the band tucks the tie, as before described. G represents aspring upon the end of rackbar a, which is compressed as it is drivenforward. As soon as the shaft t stops in its motion the recoil of thespring will withdraw the rack-bar a and the tucker X Y shown in Fig. 9.The ratchet and pawl attached to the gear B allows it to revolvebackward upon its shaft T when the revolution of the shalt ceases. Theoperation is completed just as the arms M M are. ready to leave theirupright position, as they are shown in Fig. 12.

N represents a spring attached between the joint of the arms, the recoilof which brings them into therhorizontal position shown in Pinion B isattached to the shaft t by' Fig. 7, where they are readyto receive asecond bundle, which is intermittently thrown upon the bent arm P by theaction of the reel S, as before described.

I claim 1. A harvester frame composed substantially ofthe oscillatingframe B, on which the drivers seatis mounted, and supporting-frame O G,the crank-shaft E, wheels A E, and mechanism on the oscillating framefor raising and lowering the supporting-frame, substantially as hereinset forth.

2. In a harvesting-machine, the oscillating frame B, supported upon thedriving-wheel and attached to the main frame by axial bearings b b,through which the transmittingshaft passes and imparts motion to theoperating mechanism, substantially as herein set forth.

3. The oscillating frame B, supported upon the ground-wheel A andpivoted to the main frame upon a transmitting-axis, in combination withthe supportingframe 0 and the Windlass F on the oscillating frame, forraising and lowering the frame, substantially as herein set forth.

4. The combination of a crank-shalt and the main frame arranged thereon,and supporting the operating mechanism of a harvester, and capable ofrising and falling in a vertical plane, with the oscillatingsupplemental frame pivoted to said main frame and connectedwith saidcrank-shaft, and a drive-wheel attached to the oscillating frame andimparting motion to the mechanism located on the main frame, allsubstantially in the manner and for the purpose described.

5. In combination with the reel Sand curved apron R, the chute-rods Rand the hinged rod 1', catch 1", and spring 1', for checking thedelivery of the grain andallowing it to be deposited intermittently inbunches, in the manner substantially as herein set forth.
